Many of the less expensive SDR dongles, including the ones we acquired via
group-buy, have an unpopulated spot for a protection diode right next to
the antenna jack. This is probably fine for the little antennas they
shipped with. If you intend to hook yours up to a more powerful antenna, I
advise holding off a little.
I ordered a good quantity of BAV99 (what's supposed to be in that spot on
most designs) and will drop a supply at the space once I receive them (they
already shipped from California, so it should be soon). I'll drop enough
so that everyone can grab a couple in case of soldering errors. If anyone
got some of these outside of the group buy, let me know, and I'll bring
extras for you too.
I'll post about where they are after I've deployed them at the space.

Good question... I possess even greater ignorance though! (total RF newb
here) Anyone else know if grounding the antenna provides sufficient
protection? --Greg

Here's my setup - I cut the cable last year and am exclusively getting OTA
HD TV. I have a roof mounted HD antenna running into a three-way splitter -
two going to my TiVo and the other going to my TV (backup in case the TiVo
flakes out). I am going to remove the cable going from the splitter to the
TV and run it to my EzCap. The antenna is also run to a grounding spike.

I've dropped off a bunch of BAV99 diodes for the SDR people at the space.
They're on the peg-board rack to the right of the soldering stations. If
someone needs to relocate them, please reply and let the others know where
to. If I did my math right, there should be two diodes for each tuner
purchased, so everyone gets a spare in case of error.
